IMPROVEMENT IN EVELETING-M ACHINES;

Specification forming part of Letters Patent No. 122,366, dated January 2, 1872.

To all whom it may concern:

Be it known that I, OLIVER G. GRITCHETT,

of Stoneham, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in E yeletin g-Machines and I do hereby declare that the following, taken in connection with the a drawing which accompanies and forms part .of this specification, is a description of my invention sufiicient to enable those skilled in the art to practice it.

My invention relates to the organization and method of driving the mechanism. of an eyeleting-machine. In common eyeleting-machines, or those of the more approved kinds, there are the following instrumentalities: A rotating eyelet-box or hopper; a verticallyreciprocating eyelet-pin and set that receive the eyelet and set it against a stationary set; and an inclined reciprocating chute.

These machines are usually worked by the reciprocations of a lever and pedal mechanism; and the process of setting eyelets by them is slow, tedious, and not thoroughly effective; and the primary object of my invention has been to so connect the parts with a rotary shaft that the intermittent rotative movement of the hopper, the reciprocating movement of the hopper and chute, and the vertically-reciprocating movement of the setting-tool may all be effected by the continuous and unin termittent movement of said shaft; and my invention consists primarily in combining the horizontally-reciprocating chute, the rotating hopper, and the vertically-reciprocating setting device wit-ha shaft in such manner that the rotative movement of the shaft elfects all of the movements of the machine. The invention further consists in so combining and arranging the mechanism that the chute first goes forward and brings the eyelet at its lower end directly over the receiving-pin; the chute then stops and the pin ascends, passing into and through the stationary eyelet; the chute next draws back,

, leaving the eyelet on the pin, and the pin next rises with the eyelet,'and while so rising the chute is stationary, the chute being stationary during the setting operation, and the setting mechanism being stationary when the chute goes forward, and when it draws back after the eyelet is received upon thepin.

The drawing represents a machine embodythe improvements, A and Bbeing, respectively, opposite side elevations, andO being a front View.

a denotes a stationary frame; b, a horizontal shelf upon the same, upon which shelf is supported and slides the bottom plate 0 of a triangular frame piece, 01, having on its inclined top the chute or roadway 6, made in the usual way, and provided with the usual eyelet-box or hopper, which holds the eyelets, and by its rotative'movement keeps the chute sufficiently filled with eyelets. The chute-plate or frame slides horizontally upon the top of the frame a, and is guided and kept in place by a sta tionary pin, f, which extends through a slot, g. At the rear end of the chute-board or frameis a tail piece, h, from which extends a pin, '5, into a cam-slot, k, in one side of a cam-wheel, l,

fixed on a rotary cam and driving-shaft, m. n

denotes the vertical shaft, on top of which is formed the movable eyelet-set 0, which acts in conjunction with the stationary set 12 to clinch or set the eyeletwhen the shaft is raised. In the shaft n is the spring-pin g, which passes throughor impales the eyelet at the end of the chute, the pin yielding against the stationary pin T when the set 0 rises. The shaft n is j ointed by a link, s, with one arm, 15, of a bent rockerlever, fulcrumed at u, whose other arm has a pin, o, projecting into a cam-groove, w, in the cam-wheel l on the shaft m. Another arm, :0,

extends from the lever, and is connected by a link, y, with an arm projecting fi'oin'the shaft or pin on which the eyelet-box z is mounted. As the shaft m is rotated the cam 7p actuates the chute, and the cam w actuates the movable eyelet-set and the eyelet-box or hopper, the operations being continuous and requiring no cessation, as in pedal-operated machines, the

operations of the machine being more uniform and certain than by the spasmodic operations ofthe old machines. The formation of the cams k and w are such that, when the set 0 is down to its lowest position and at rest, the

chute is thrown forward and brought to a stop; the set 0 is then moved up, the chute being stationary, and the pin enters the lowermost eyelet of the chute; the set then stops and the chute retreats; and the chute then stops and the movable set rises, the chute being stationeyelet er yi, pin-impaled 'eye1'et,;a:n'd the-exelet is set. "The set then desdeifcls, the Tchute being still stationary, and. the parts are then in position for the chute again to advance for presenting another eyelet to the pin. 7 i lnoperetiqg an eyelet-machine by a pedal mechanism the movement of thelowei' or movable set is greater or'less, iii accordance With the thickness of the stock. But in the camoperated machine the throw of the movable set is necessarily constaiht or positive in extent and if the sets come together when no stock is-in the machine the lower set, of course, could not reach the highest ptmtof its meow when "stock 5 7 is interposed unless provision is made forsome suitable spring, substantially as described.
